FEATURES
74AVCM162834
PIN CONFIGURATION
• Wide supply voltage range of 1.2 V to 3.6 V
• Complies with JEDEC standard no. 8-1A/5/7.
• CMOS low power consumption
• Input/output tolerant up to 3.6 V
• Low inductance multiple VCC and GND pins for minimum noise
and ground bounce
• Integrated 15 Ω termination resistors to minimize output overshoot
and undershoot
• Full PC133 solution provided when used with PCK2510S and
CBT16292
DESCRIPTION
The 74AVCM162834 is an 18-bit universal bus driver. Data flow is
controlled by output enable (OE), latch enable (LE) and clock inputs
(CP).
This product is designed to have an extremely fast propagation
delay and a minimum amount of power consumption.
To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pullup resistor (Live
Insertion).

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + S (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V; S (CL × VCC2 × fo) = sum of outputs.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
